Abstract

A video storage type communication device which is capable of storing coded video data received from a terminal and reproducing required video information by rapid forwarding or reversing at any desired frame rate at the terminal independent of the terminal specification. A video storage type communication device which comprises a transmitting portion (17) for transmitting video data and a receiving portion (11) for receiving video data over a communication line, a video storage portion (15) for storing received video data and a communication control portion (14) for carrying-out video-communications by controlling the above-mentioned portions. The device is further provided with a refresh image detecting portion (12) for judging, from the received coded video data, whether the received coded information is a refresh image, a storage control portion (13) for storing into the video storage portion (15) the coded video data received by the receiving portion (11) by previously adding thereto inter-frame or intra-frame prediction coded information detected by the refresh image detecting portion (12) and a terminal control portion (20) for sending at a desired interval a request for updating display image through a communication control portion (14) to a terminal during storing video information.
